PORTABLE CLEANING DEVICE.

Patented June 2U, rare.

Application filed March 27, 1915. Serial No. 17,471.

and useful Improvements in Portable Cleanmg Devices, of which thefollowing is a specification.

This invention relates generally to cleantable device for discharging aliquid detergent under pressure which renders the same particularlyuseful for removing grease, oil,

. same by a scraping tool.

and the like from automobile and other en- "gine parts.

1 It is particularly desirable in repairing parts of motor car enginesand like surfaces which may be coated with grease, oil, and dirt, thatthe same be cleaned easily and quickly without dismantling the entiremechanism and placing the individual pieces in a bath of gasolene orsimilar cleaning liquid. Furthermore, it is not always convenient orpracticable to remove the grease with cotton waste or otherwisedisplace'the Therefore, the present invention contemplates a novelportable container or vessel for a cleaning liquid, such as gasolene,coahoil, or the like, which may be connected with a suitable source ofcompressed airsupply to force the detergent agent onto the surface orarticle to be cleaned through a conveniently inanipulated handnozzle.

To this end, the invention contemplates a substantial and practicalconstruction of container or tank having a novel arrangementof air andliquid controlling valves which may be easily and quickly manipulatedand minutely adjusted to regulatethe supply of cleaning fluid forcedfrom the container.

While the invention is primarily intended for use in cleaningoperations, it may be also provided with suitable instrumentalitieswhereby it may be readily converted and used as a blow torch.

With the above and other objects in View which will more readily appearas the nature of the invention is better understood, the same consistsin the novel construction, combination and arrangement of partshereinafter more fully described, illustrated and claimed.

A preferred and practical embodiment of the invention is illustrated inthe accompanying drawings, in which- Figure 1 is a perspective view ofthe invention showing the novel valve arrangement and brush nozzle. Fig.2 is an enlarged detail sectional view showing the in-, teriorconstruction of the tank and valve device. Fig. 3 is a detail sectionalview of the discharge nozzle.

Similar reference characters designate corresponding parts throughoutthe several figures of the drawings.

In the embodiment of the invention disclosed in the drawings, the sameessentially comprises a suitable container or tank 1 which may be of anyconvenient form or size and preferably provided at its lower end with abase support 2 for permitting the same to stand on end when in operativeposition. To facilitate the handling and port ability of the tank, theremay be provided a swinging bail or handle 3, and also to en- .able thetank to be filled with the cleaning liquid or fluid, the same isprovided with a siliitable filler spout 4 having a closure p ug 5. v

Detachably fitted in the head 6 of the tank is a combination air intakeand liquid discharge valve device designated generally by the referenceletter V, and comprising'a hollow valve casing 7 formed with a centralcap portion 8 and the oppositely disposed nipple extensions 9 and 10.The casing 7 als0'includes a hollow shank portion 11 which may beprovided with suitable threads 12 tb enable the same to be screwed intothe head of the tank, thus facilitating the fitting and Y removal of theentire valve device from the tank when repairs thereto are necessary.The greater portion of the shank 11 extends down into the interior ofthe tank 1 and has a plurality of air ports 13, thus establishingcommunication between the in terior of the valve casing and the interiorof the tank. I I

Arranged within the valve casing 7 and extending through and beyond theshank portion 11 is a liquid supply pipe 14 which is of less-diameterthan the shank 11 thus providing an annular air space or chamber 11between the walls of the shank and the exterior of the liquid pipe. Thisliquid pipe 14 is preferably threaded at its upper end as at 15'so thatit may be screwed into the central cap portion 8 of the valve casing,

trol a-port 20Iin' the pipe 14 which is in communication with alaterally disposed liquid delivery tube 21 extending into the,

nipple extension 10.

' In connection with the oppositely disposed nipple extensions 9 and 10of the valve casing it will be observed that the former has fittedthereto an air intake valve 22 while the latter has fitted thereto asimilar type of outlet or discharge valve 23. These valves 22, and 23when fitted to the valve casing as above explained cooperate therewithto provide an air pressure receiving chamber 24 and a delivery chamber25 which are in direct communication with each other andalso incommunication with the annular chamber 11.

In use the tank or container 1 is fitted with a suitable cleaningliquid, gasolene, coal oil,

or other fluid capable of removing grease,

' and the valve 22 is connected by means of a hose or tube toa source ofcompressed air supply. When the plug of this valve is opened, air willenter the. chamber 24 and pass down into the annular chamber 11 and outof the ports 13 thus forcing the liquid up through the pipe 14 and alsothrough the delivery tube 21, and into the chamber 25 where it isejected or forced out through the discharge valve 23 into suitable meansfor applying the liquid to the parts to .be sprayed and cleaned, suchfor instance as a flexible hose 26 having thereon a hand nozzledesignated in its entirety by the reference 27. This hand nozzle 27preferably includes a hand grip 28'and a stem 29 having at its open enda detachable discharge nozzle 30 which is preferably provided witha'wire brush or equivalent element for augmenting the cleaningoperation.'

, From the foregoing description, it will be apparent that the novelvalvedevice makes special provision for supplying a cleaning liquid to ahand nozzle under pressure, the volume of which liquid can at all timesbe easily regulated independent of a constant air pressure supply. Infact, where the ocsion demands, the liquid supply can be entirely cutofl and thehand nozzle discharge only air or practically a solid streamof liquid may be discharged. Furthermore, this valve arrangement givesthe present device another utility, namely, that of a blow torch, aridto provide for this adaptation of the device, the tank 1 has arrangedtherein a blow tube 32, the exposed end of which is normally coveredduring the use ofthe device as a cleaner by a blank plug or cap 33.However, this plug may be easily removed and any standard type of torchburner inserted in its place.

When the device is used as a blow torch the valve 23 is closed, and theport 20 of the tube 14 is also closed, and the blow torch elementinserted in the end of the tube 32. The valve 22 is then-opened and putin communication with a compressed air supply, and the compressed airallowed to fill the tank to capacity. The valve 22 is then closed thusholding the liquid under ressure and rendering the device capable odischarging the usual igniting fluid for the torch.

Without further description, it is thought that the many features andadvantages of the invention will be readily apparent, and it will ofcourse be understood that various changes in the form, proportion andminor details of construction may be resorted to without departing fromthe spirit of the invention or scope of the appended claims.
